DeepL MCP Server

An open-source Model Context Protocol (MCP) server that provides text translation and rephrasing via the DeepL API. It allows AI applications and other clients to access DeepL's language services programmatically.

Overview

This server acts as a bridge between MCP clients and DeepL's translation engine. You can connect to it from any MCP-compatible client to translate or rephrase text across numerous languages.

Connection URL: https://mcp-servers--deepl-mcp-server.apify.actor/mcp

Key Features

• Translation: Convert text between a wide array of languages.
• Rephrasing: Adjust the style and tone of text in the same or a different language.
• Language Support: Access to all DeepL API languages, including English, German, Spanish, French, Japanese, Chinese, and many more.
• Automatic Detection: The API can automatically detect the source language of your text.
• Formality Control: For supported languages, you can specify the desired level of formality in the translation.
• Tool Discovery: Built-in tools to list all available source and target languages.

How to Use

To connect, add the server configuration to your MCP client. You will need a valid Apify API token.

1. Get your Apify API token from the Apify Console.
2. Configure your MCP client with the following settings:

{
  "mcpServers": {
    "deepl": {
      "url": "https://mcp-servers--deepl-mcp-server.apify.actor/mcp",
      "headers": {
        "Authorization": "Bearer YOUR_APIFY_TOKEN"
      }
    }
  }
}

Replace YOUR_APIFY_TOKEN with your actual token.
